I'm about to fit a Wizards of Nos kit with progressive controller to my 323 with M50 manifold.
The kit is currently a single injector system. Looking at the M50 manifold, it would probably be best in the long run to upgrade to direct port with 6 injectors.
So who has run nitrous on this engine and what sort of jets have you been running? Be interested to hear from anyone running single point up to a 75 shot. Where you have positioned the injector etc?
